The unfortunate rise in death rates during the winter season is certainly a cause of concern. The cold weather can sometimes turn brutal and lead to heart issues which can prove fatal.

Talking along the same lines, an expert on Tuesday listed several factors like drop in body temperature, decreased level of vitamin D in the body and an increase of blood viscosity, saying that they may heighten the risk of cardio-vascular diseases during the winter season. Besides the temperatures facing a downward plummet during winter, high winds and rain often reduce the body temperature, due to which there is a sudden rush in the blood pressure leading to a heart attack. Low body temperature in winter may increase blood viscosity which increases the risk of clot formation. “Individuals above the age of 40 are at a higher risk of heart attacks. There are a number of factors which may trigger a heart attack during winter, starting from hypertension to obesity. Increasing cholesterol levels, diabetes or excessive smoking may put you on the radar,” said Prithwiraj Bhattacharya, Associate Consultant Cardiologist, Fortis Hospital, Anandapur. Scarce sunlight during winter may decrease levels of Vitamin D in the body. There are a number of physiological mechanisms triggered by vitamin D production through sunlight exposure that fight heart disease. An imbalance in any of these puts the heart in danger. Bhattacharya also said there is a rise in blood pressure during early morning which further leads to a heart attack.
